“…The procedure must be carried out using the design spectrum given in the code for a structure created at a project site. For dynamic analysis of steel and reinforced concrete buildings, the damping values for buildings may be regarded as 5 % of the critical value [16][17][18]. An inelastic analysis is more appropriate for design because it can be anticipated that an inelastic response will happen during a big earthquake for most buildings.…”

The resistivity of lateral forces (Wind and Seismic loading) by any structure is very much challenging. It is also one of the reasons for the failure of the reinforced concrete (RC) structure due to its asymmetric distribution of mass, strength, stiffness, and non-uniform geometrical configurations. Knowing the effect of various soils in the construction of RC structures is essential to determine the structural performance in the presence of seismic load ahead of construction. This research aims to compare regular and irregular RC structures in different seismic zones, and soil types with the provisions suggested in IS code 1893(part1):2016 and IS 875(part3):2015 using STAAD Pro V8i. Research work calculated the critical design loading for multi-story buildings put through basic wind speeds of 50 m/s and seismic zones (II, III, IV, V). The response of a G+20 storeyed RC framed building to seismic loads is examined using Indian Standard code IS 1893(part1):2016 and wind loads using Indian Standard code IS 875(part3):2015.

Large‐scale multiaxial testing facilities mainly serve to experimentally examine the horizontal behavior of full‐scale critical structural members, such as columns and seismic isolation bearings, on which a large vertical compression load is exerted as they simultaneously undergo horizontal deformation. The system friction and inertia force play an important role in obtaining sufficiently reliable test results, and it is not easy to comprehensively grasp all the issues involved. To understand the system friction and inertia force of the Bi‐Axial Dynamic Testing System (BATS) at the National Center for Research on Earthquake Engineering Tainan laboratory and to avoid complexity caused by specimens as much as possible, a lubricated flat sliding bearing is chosen as the specimen to be tested under horizontal triangular and sinusoidal reversed loading together with a constant vertical compression load. When no specimens are installed, that is, without vertical compression loading, the system friction of BATS generated by the various sliding surfaces can be identified and mathematically characterized using the horizontal triangular reversed loading test results; then, the effective mass of BATS can be estimated using the horizontal sinusoidal reversal loading test results to solve the inertia force problem. When applying a vertical compression load, it is assumed that the system friction of BATS and the shear force of the specimen are simply related to the applied total normal force (or vertical compression load) and horizontal excitation rate. An iteration methodology is proposed to identify and mathematically describe the dependency of the friction performance of BATS and the specimen on total normal forces (or vertical compression loads) and horizontal excitation rates by iterating the horizontal triangular and sinusoidal reversed loading test results. Finally, a lead‐rubber bearing and a direct force measurement system are connected in series such that the measurement system precludes the system friction and inertia force and a series of tests are conducted. The reliability of the proposed mathematical model for BATS and the feasibility of the proposed direct force measurement strategy are further demonstrated by comparing the calibrated force response with the directly measured response.
